Abstract

Une unité de filtre (100a) selon la présente invention comprend : un filtre (111) ayant une forme de prisme rectangulaire et filtrant les poussières de l'air ; un cadre de support (120) ayant une forme de prisme rectangulaire, logeant le filtre en entourant les bords du filtre, et ayant une surface avant et une surface arrière qui sont partiellement ouvertes ; et des éléments de fixation (130) couplés de manière fixe sur le cadre de support et fixant le filtre sur le cadre de support. Étant donné que l'unité de filtre (100a) a des éléments de fixation réglables (130), il est possible de fixer aisément le filtre au cadre de support (120), et ainsi d'assembler et de remplacer le filtre de manière simple. En conséquence, puisqu'il est possible de ne remplacer que le filtre, les coûts de maintenance peuvent être réduits.
